How to build an eCommerce mobile app

Before you learn how to create an eСommerce app, you need to know what it is. An eCommerce mobile app is an application through which people can buy or sell goods in a few clicks using their mobile phones.

eCommerce is becoming one of the most popular types of entrepreneurship in recent times. It can refer not only to the sale of goods but also to the provision of various services. So we see that new opportunities are opening up for many types of businesses.

Growing competition in the global market motivates companies to use an innovative approach to create a positive consumer experience. Namely, to develop mobile applications for establishing mobile sales channels.

In eCommerce, these effective solutions should combine an exciting set of features without limiting consumers to a single “add to cart” function. Also, such solutions should provide the ability to complete a transaction in one click while remaining attractive to the buyer, encouraging subsequent purchases.

Build eCommerce app: Trends and Facts in 2022

eCommerce Trends

eCommerce Trends

How to build an eCommerce mobile app that will be in demand and popular? To begin with, we recommend that you study the trends of this market. Let’s look at the main ones in 2022.

Quick facts about eCommerce mobile applications

  • 53% of smartphone users buy from branded apps
  • The conversion from mobile apps is three times higher than from mobile sites.
  • About 82% of internet users in the US use mobile devices to shop online.
  • 42% of smartphone users plan to shop more on mobile apps in 2022.
  • Mobile shoppers spend twice as much money as other shoppers.
  • According to an eMarketer report, The Future of Retail, the growth of e-commerce will reach $845 billion in 2022.

Top trends in the eCommerce mobile app market in 2022

And before moving on from how to create eCommerce app to building an eCommerce mobile application, you should first find out the major trends in the eCommerce mobile app market in 2022: 

Chatbots

Many well-known companies, such as Spotify or Lyft prefer to use chatbots to communicate with customers. According to some statistics, 54% of consumers prefer to contact sellers and brands using chatbots rather than phone calls. Chatbots make it possible to communicate with customers 24/7.

Also, because such modern technologies as AI and ML have become available, chatbots can receive and analyze customer data. This helps predict what next question, for example, the clients will ask and what better answer to give them.

Omnichannel marketing

As a major trend in modern eCommerce, the purpose of omnichannel marketing is to provide customers with chances for fulfillment from wherever they want to purchase. From smartphone to in-person purchasing, omnichannel marketing allows customers to interact with companies on their own terms via a single, convenient channel.

Personalization

To feel relevant nowadays, customers want much more than their name at the top of a marketing email. People want to be heard and want companies to provide them with information that is relevant to their needs – at the appropriate time and in the right location.

Brands can guarantee customers see what they’re genuinely interested in by customizing their advertising with bespoke targeting, generating relevance, engagement, and conversions.

Voice assistants

Everyone knows the voice assistants Siri and Alexa. Voice search is very convenient in online shopping. According to some statistics, 51% of consumers use voice search to find the goods they need, and 22% to order. 

Why Do You Need To Build an eCommerce Mobile App?

Build an eCommerce Mobile App

Why should you know how to build an eCommerce mobile app and start building it anyway? We have prepared some convincing facts for you. Let’s look at them in more detail, and you will know how to create an eCommerce app. 

Always at the customer’s fingertips

Creating an eCommerce mobile application will make it possible for users to shop anytime, anywhere. Very often, people standing in lines or in traffic jams use their phones to pass the time. It would be great if, at that time, they could use the eCommerce mobile app to make the purchases they require.

High level of service offered

You automatically offer users a new level of service and a better one if you know how to create an eCommerce app. As a result, new opportunities open up for customers, namely, to buy goods and place orders online anywhere in the world and at any time.

Attracting a new audience

By opening up new opportunities for people, you attract a new audience. For example, young people prefer to use mobile phones more than computers because they are more convenient, faster, and more affordable.

Gaining clients trust

By offering people an eCommerce mobile app with a good security system, for example, you increase user trust in you. But the most important thing is the security system. Without it, it won’t be easy to prove to the user that your eCommerce mobile app is a safe place to shop and place orders.

A new level of communication

Mobile applications are always about fast and high-quality communication. If you know how to create an eCommerce app and build it, you can be with customers 24/7. This becomes a significant advantage.

Chance to expand business

By creating an eCommerce mobile application, you will automatically make an opportunity for the future growth of your business. Over time, you will be able to expand the capabilities of your application, thereby offering your users a more comprehensive range of services and better quality.

Additional marketing channel

By providing users with access to your business through a mobile application, you open up another marketing channel for your company, as well as increase the effectiveness of existing marketing. You also get extra space for ads, sales funnels, conversion strategies, etc.

Covid-19 and worldwide trends

With the advent of the Covid-19 pandemic, people have become more likely to shop online. Also, new trends began to appear related to the world’s transition to online mode. Therefore, switching to a mobile application will allow your business to be in trend and meet modern realities.

Build eCommerce app: Design Challenges

guide 1 2048x1137 1

How to Build an eCommerce Mobile App

How to build an eCommerce mobile app without any challenges? Actually, not at all. Any process, and especially the creation of a new product, includes several challenges. Let’s first look at the design challenges:

Usability

The first thing you need to know in a how to build an eCommerce mobile app question is usability. To make the user experience of a mobile app truly seamless, everything from registration to checkout should work correctly.

The usability of mobile applications is an essential part of the development and plays a vital role in creating an efficient and user-friendly user interface. If your application is useful and valuable to the users, but they absolutely do not understand how to use it, they will abandon it.

Trust for the brand

It is challenging to earn people’s trust. When creating an eCommerce mobile application, you may encounter this problem. We said earlier that nothing is more trustworthy than security. If users feel safe in your application and know that no one will steal their money, then they will definitely trust your business.

Consistency with the marketing strategy

Be sure to stick to your marketing strategy. If you don’t combine these two things, your eCommerce mobile app will certainly not work and deliver the results you expect. The more people you tell about your application, the more users you will get. Marketing is essential!

Conversion rate

This challenge is related to the previous point in a how to build an eCommerce mobile app question. The better you set up the promotion of your application through different marketing channels, the higher the conversion rate you will get. Usability and UX also affect the conversion rate.

Different CTAs and appeals can significantly increase the conversion rate. But these things need to be tested, for example, as we do in our in-house UX lab. However, we will talk about this a little later. Try different strategies, and it will not be a big problem for you.

Build ecommerce app: Development Challenges

How to Build an eCommerce Mobile App

Now let’s look at the difficulties that you may encounter during the development stage when solving a how to build an eCommerce mobile app question:

Security

Among mobile app leaders by a number of installs, 94% contain at least three medium-severity vulnerabilities, and 77% contain at least two critical vulnerabilities. Compared to other types of devices, mobile phones are the most at risk for theft or loss. 

But even if the physical copy of the device is with the user, you should be more concerned about the proper level of storage of sensitive data (confidential information, etc.) to prevent intentional and unintentional leaks.

API integration

The potential of APIs in mobile applications is vast and valuable for any business. Here are just some of the features that can be implemented in an application using external interfaces:

  • Authorization in the service through an account in social networks or a Google account;
  • A variety of online client forms (filling out an order, managing a shopping cart, etc.);
  • Currency converters and financial calculators;
  • Chatbots and means of communication between the client and the support service;
  • Integration of online maps;
  • Use of electronic wallets;
  • Mobile banking;
  • AI tools (voice recognition, for example).

API tools help businesses quickly and cheaply automate routine processes and transform legacy web services and a very popular solution in a how to build an eCommerce app in android question. At the same time, the introduction of new technology with this approach will take only a few weeks.

Scalable product

It is crucial to make the product so that it can be scaled in the future. This is directly related to the future of your business. If you want to grow your business and open up new opportunities for your customers, you should make the product scalable.

AI / Big Data integration

AI technologies will be widely used to analyze customer choice, automate, optimize resource usage, generate automatic responses to queries, and improve conversion rates. Based on the capabilities of AI and Big Data, users get a personalized experience. That is one of the key points in how to build an eCommerce app in android question.

With the help of Big Data analysis algorithms, specialists use statistics for further forecasting. Big Data algorithms also help identify the target audience, analyze user behavior, select key messages and track campaign results.

In eCommerce mobile app development, AI helps analyze shopping behavior and increase sales by providing relevant product recommendations.

Technology plays an essential role in the personalization process. The most prominent example of an application that provides a personalized experience with the help of AI is My Starbucks. Users can order a drink on the go. The chatbot makes recommendations based on the preferences of the client.

The user can place orders by voice via Amazon Alexa or through the MyBarista app and then receive them at a selected coffee shop nearby.

Develop Custom eCommerce App or Ready-made Solution

talkaru start up team business english course

How to Build an eCommerce Mobile Application

If you’re going to build an application for your business, it’s best to go with a custom-built app for better long-term outcomes. Here are some of the reasons:

Custom-developed applications are exactly that: tailored to your company’s needs.

If you choose a free or low-cost app builder, you will be severely limited in the colors, styles, and visuals used in the design. It won’t be easy to truly showcase your company and brand at their finest, as well as separate your brand from other businesses that have created their apps on the same platforms. 

A custom-built app will give you complete control over the design and user experience, allowing you to stand out from the crowd.

There are no recurring expenses for custom-built apps

If you decide to invest in a custom-made app, there is only a one-time fee for the design and development of your app. Of course, you may update or add features to your app at a later date for a price, but unlike ready-made apps, you won’t be locked into membership costs. 

Keep in mind that many free or low-cost app development platforms disable access to the app as soon as the membership is terminated, which means that all design and content is lost and should be recreated.

With a custom-built app, you can take advantage of increased promotion chances

You have total control over your custom-built application, and you can market it on the Google App Store if it is designed for the Android platform or in the Apple App Store if it is designed for iPhones and iPads. You may use paid advertising methods to bring visitors to your app’s website since you will have a dedicated homepage for your app.

You may also market your app through social media or by linking to it directly from your website. Moreover, there is a good probability that people will find your app by surprise through organic search. Unfortunately, if you choose a free or low-cost app creation platform, you may not have your own unique app URL and may not be able to advertise it directly.

Typically, these applications reside on the development platform’s own website, making them difficult to locate unless you tell your clients about them directly.

Custom-built applications can be scaled in the future

Since the custom-build application is developed entirely for you and your company, you can make changes to the product at any time. Let’s say you want to add more advanced features or improve the design.

Using a ready-made product, you will not have such an opportunity, but in the case of a custom-built application, you can change and scale the product as you wish. It is impossible to build a large and high-quality product on WordPress, so we advise you to choose the custom creation option.

How to Build an eCommerce Mobile App [Step-by-Step Guide]

4444

We have prepared a step-by-step guide in which we will tell you what the main stages of creating an eCommerce mobile app are.

1. Write a Project Plan & Requirements

The first step you need to start creating your eCommerce mobile application is writing a plan and requirements for your product. A plan is essential to keep the whole process organized and structured. By sticking to the plan, you will be able to complete the project faster and better.

The requirements for your product need to be written so that your design and development team understands exactly what they need to work on. Usually, the project requirements include the following things:

  • Full project overview.
  • Main needs and goals.
  • Target audience.
  • Functional requirements and desired set of features.
  • Aesthetic aspects.
  • Non-functional details.
  • Recommendations and prohibitions.
  • Questions.

2. Select Your App Development Partner

Next, you need to choose a good app development partner. A good and professional team is half the success of the project. There are several ways to find a team:

  • Use social networks like LinkedIn.
  • Rate a large number of teams on ranking sites like Clutch.co.
  • Ask friends and colleagues about the possible experience of working with a great team.
  • Choose Northell for fruitful collaboration!

3. Start Product Discovery

When we work on projects, we usually get involved at this stage. At this step, it is necessary to conduct a product discovery. Product discovery aims to find a product/market fit and validate the business model with a working version of the product.

Persona Example

The key way to achieve this is to consistently reduce risks by validating customer behavior hypotheses, value propositions, product solutions, business models, and acquisition channels.

4. Start to build a UX Design

The goal of UX design is to create a digital product that the user will feel comfortable with. This includes how the product functions and the user manages it: content hierarchy, clear navigation, and the functionality of visual elements. 

But the most important thing is that all this helps solve the user’s problem. In addition, the design should be created in accordance with technical and business specifications. Here are the steps that the UX design process usually consists of:

1. Product definition

  • Stakeholder interviews
  • Value proposition mapping
  • Concept sketching

2. Research

  • Individual in-depth interviews 
  • Competitive research

3. Analysis

  • Creating user personas
  • Creating user stories
  • Storyboarding

4. Design

  • Sketching
  • Creating wireframes
  • Creating prototypes
  • Creating a design specification
  • Creating design systems

5. Validation

  • Testing sessions
  • Surveys
  • Analytics

5. Start UI Design

UI design is the process of visualizing a prototype that was developed based on user experience and target audience research. UI design includes work on the graphic part of the interface: animation, illustrations, buttons, menus, sliders, photos and fonts.

UI design is responsible for how the product interface looks and how the user interacts with its elements. It is necessary to correctly organize the interface elements and maintain a single style and logic of their interaction.

Your main task is to help the user understand how to use the product quickly and without stress. To do this, you should ensure that the interface meets the basic requirements.

6. Do a User Testing

After the design is completely ready, you can start testing. Never skip this step. The more detailed you test the product, the more likely your application will work like a Swiss watch.

At Northell, we use our in-house UX Laboratory that helps analyze how people interact with the interface and uncover products’ usability gaps. 

We use UX Eye Tracker, which allows exploring user behavior during interaction with the product. Only 1% of companies use this method. To know more about our UX Lab, click here.

7. Build a Development Process [SDLC]

How to Create a Money Lending App:

How to Build an eCommerce Mobile App

Now comes the most crucial stage. You need to turn the design into a real working product and become closer to starting a loan app. We divided the entire development process into several steps. Let’s take a closer look at each of them.

Product Technical Documentation

During this stage, all the relevant information from the client is collected to develop an application as per expectations and requirements. The team should write technical documentation and choose technical stacks.

At this stage, the team should also define the requirements for functionality (requirements for the admin panel) and user roles (admin and super admin). The team should complete the estimate and scope of work.

Development

Using the documentation and architecture from previous steps, mobile app developers write code for the components. We divide the tasks between the team members according to their area of specialization. 

Testing

QA engineers test all delivered code and carry out manual testing for developed components.

Deployment & Integration

After the development and regression testing from the QA team, the team switched to production deployment and integration. The tested version of the product is delivered to the users for beta testing. The team collects user feedback, fixes all the bugs, and implements some improvements.  

Maintenance

After deploying a product in the production environment, maintenance of the product, i.e., if any issue comes up and needs to be fixed, or any improvements are to be done, it is taken care of by the development team.

8. Launch

Now is the time for the market to see your eCommerce mobile application! The product launch process causes meticulous preparation and should be carried out systematically to guarantee that clients accept the product favorably. The following are the major steps to start an eCommerce mobile app:

  • Target audience identifying.
  • Unique product packaging creation.
  • Slogan and timeline creation.
  • Competitors analysis. 
  • Customer onboarding creation.
  • Website creation.
  • Advertising.

Core Features in Your eCommerce Mobile App

190306 virtual marketplace concept

How to Build an eCommerce Mobile App

And now, let’s look at the list of the main features that you should add to your eCommerce mobile application.

Personal account 

A personal account is the heart of any eCommerce application. This feature should allow users to fill in personal details, view their shopping cart and purchase history, and generally make purchases or sales.

Apple pay / Google pay 

Your eCommerce application should have the ability to pay for goods using Apple Play or Google Play. Today’s youth, for example, often use these payment methods.

Checkout process

Without this feature, users will not be able to use the primary purpose of the application – the purchase of goods. Therefore, it is very important to make this feature easy to use and understandable for the user.

Smart filters

This feature is needed so that users can quickly find the product they need. These filters should contain as many criteria as possible. The faster the user achieves the goal, the better the user experience will be.

Chatbot

As we mentioned earlier, chatbots are trending in 2022. Therefore, you should add a chatbot to your platform. It will help automate many processes and make communication with users better.

Reminder and notification system

This feature will help users to always be aware of what, for example, is happening with their order (the order is accepted, the order is being collected, the order has been sent). Of course, if users don’t want to receive notifications, they can always turn them off.

Discount system

This feature is one of the most attractive for users. It will allow, for example, people to buy goods with a particular discount for any holidays. Or let’s say you can make seasonal discounts for users. There are a lot of options for implementing this feature.

AR/VR Size Advisor

This feature greatly improves the user experience. Users will be able to try on any clothes, for example, without leaving their homes. They will only need to use the camera of their phone. This feature has already been implemented by many well-known brands such as Nike, Adidas, Hugo Boss, etc.

Biometric identification

To identify the user in the application, you can use biometrics – for example, scanners of the iris, facial geometry, or a fingerprint. The use of such technologies is now very popular.  

Real-time information 

This feature allows you to show information about the users’ orders in real-time. That is, each action that is carried out with the order will be displayed in the user’s personal account. For example, the goods were packed, the goods were sent, the goods are already in your city, etc.
